This is an industrial USB to RS485 converter from Waveshare with an original FT232RL chip. The USB to RS485 converter is very easy to use, allowing automatic sending and receiving of data via RS485. With this RS485 adapter, you can control Arduinos via a PC that are connected via RS485. The installation is very simple; first, install the drivers for the FT232R, and then you can select the serial USB port and send data to the RS485 via a serial console.
